Abstract

Strong resonant self-action of radiation, saturation of Stokes signal amplification and pump field absorption, and dynamic Stark effect result in a complex dependence of a refractive index and amplification/absorption coefficients on intensities and frequency offsets of the pumping and generated radiation in the active medium. Numerical simulation of propagation of diffracting FIR and pumping waves enables to investigate the influence of nonlinear beam interaction on the effectiveness of generation and to optimize energetic and spatial characteristics of the output FIR radiation.
